当我的应用程序收到通知时打开屏幕背光

当我的应用程序收到通知时，需要打开屏幕背光。我听到声音，LED指示灯亮起，但屏幕仍保持关闭状态。当我的应用程序收到通知时打开屏幕背光

我试着使用PowerManager：

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag"); 
wl.acquire(); 
..screen will stay on during this section.. 
wl.release();

但没有结果。

通知代码如下所示：

public void showNotification(String contentTitle, String contentText) { 
    int icon = R.drawable.notification; 
    long when = System.currentTimeMillis(); 



    Notification notification = new Notification(icon, contentTitle, when); 


    notification.flags |= Notification.FLAG_AUTO_CANCEL; 
    notification.defaults |= Notification.DEFAULT_LIGHTS; 




    Intent notificationIntent = new Intent(this, myapp.class); 
    Context context = this.getApplicationContext(); 


    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 
    notification.setLatestEventInfo(this, contentTitle, contentText, contentIntent); 

    NotificationManager nm = (NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE); 




    Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); 
    v.vibrate(300); 

    notification.sound = Uri.parse("android.resource://" + context.getPackageName() + "/" + R.raw.sonar_ping); 

    notification.flags |= Notification.FLAG_SHOW_LIGHTS; 
    notification.ledARGB = 0x00000000; 
    notification.ledOnMS = 0; 
    notification.ledOffMS = 0; 

    nm.notify(1, notification); 




}

如何打开时，屏幕上的通知显示在状态栏？我需要在这段代码中添加什么来实现它？

感谢您的任何建议和帮助。

试试这个

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
    PowerManager.WakeLock wakeLock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK | 
      PowerManager.ACQUIRE_CAUSES_WAKEUP | 
      PowerManager.ON_AFTER_RELEASE, "WakeLock"); 
    wakeLock.acquire();

和`吨忘记释放它。
